Star Trek is about the peacekeeping attempts of mankind. Man has been venturing far in space for not very long. They meet the Vulcans, as they help them along the way. That was mainly Star Trek: Enterprise stuff there. Later, James T. Kirk and Spock take command of the starship "USS. Enterprise". Next Joan Luc Picard took command. They all had to deal with the limitations of mankind like we all do, but they had to try to break those barriers.
